An electrical switch (40) comprises: electrical contacts (18, 20, 24) and an actuator (26) for moving the contacts relative to each other between an open state and a closed state. The actuator (26) includes a deformable member (14), preferably a cantilever, which includes a piezoelectric material (26) which is operable to undergo a dimensional change in response to an electric field applied thereacross for moving the contacts (24) relative to each other. The deformable member (14) is microfabricated from a first substrate (46) which is joined to a second substrate (12) including at least some of the contacts (18, 20) to form an assembly.
La présente invention concerne un commutateur électrique (40) comprenant : des contacts électriques (18, 20, 24) et un actionneur (26) permettant le mouvement des contacts les uns par rapport aux autres entre un état ouvert et un état fermé. L'actionneur (26) comprend un élément déformable (14), de préférence une partie en porte-à-faux, qui comprend un matériau piézo-électrique (26) pouvant être soumis à une modification dimensionnelle, en réponse à un champ électrique appliqué à travers ce matériau, afin de déplacer les contacts (24) les uns par rapport aux autres. L'élément déformable (14) est microfabriqué à partir d'un premier substrat (46) qui est joint à un second substrat (12) qui comprend au moins certains contacts (18, 20), afin de former un ensemble.
